Answer & Explanation

 

1.4

First number = 40 × 3 – (41 × 3 – 45)

= 120 – 123 + 45 = 42

 

  1. 5

P[(1 + R/100)^3 – 1] = 868 — (I)

P[(1 + R/100)^2 – 1] = 544 — (II)

 

Divinding eq I by II and put, q = 1 + r/100

(q^3 – 1)/(q^2 – 1) = 868/544

[(q – 1)(q^2 + q + 1)]/(q – 1)(q + 1) = 217/136

(q^2 + q + 1)/(q + 1) = 217/136

q^2/q+1 = 81/136

136q^2 – 81q – 81

q = 9/8

1 + r/100 = 9/8

r = 1/8 * 100% = 12 1/2%

 

  1. 2

Quantity of gold to be added

50 (95-80)/(100-95) = 50*15/5 = 150 gm

 

  1. 1

Required answer

= [y{D – (d1 + d2)} – d2x]/ x

Where

y = 20

x = 80

D = 64

d1 = 36

d2 = 2

= [20{64 – (36 + 2)} – 2 * 80]/80

= (20 * 26 – 160)/80

(520 – 160)/80 = 4 1/2days

 

  1. 4

Speed of other train = 60 sqroot[(6 2/3 / 3 3/4)]

= 60 sqroot[(20/3 * 3 4/15)]

= 60 * 4/3

= 80 km/hr

 

  1. 2

Let the distance be x km

x/12-4 – x/12 + 4 = 5

x = 80km

 

  1. 1

Let breadth = x m and length = 3/2 km

x * 3/2x = 3/2 * 10000

x^2 = 10000

x = 100 m

Length = 3/2 * 100 = 150m

 

  1. 2

Total surface area = (sum of all three sides)2 – (Diagonal)2

= (24)^2 – (18)^2

= 42 × 6 = 252 cm^2

 

  1. 1

Required number of ways = 2 × 4! × 4! = 1152

G + D —- 7 + 4 = 11,

H + D —- 8 + 4 = 12,

F + G —- 6 + 7 = 13,

H + F —- 8 + 6 = 14,

J + F —- 10 + 6 = 16

Hence, JF does not belong to the group. Become the sum of the letter is perfect square.
